"I think we've got as good a chance as anyone to win again," the St. Louis Blues center said Thursday at All-Star Media Day. "I'm very confident in that. But at the same time, it comes with a lot of work. That's our mindset. We can't win a Cup right now.
"It's starting by building and building. Yeah, we want to be playing our best hockey by the time playoffs comes. Take it one game and one series at a time."

At the All-Star break last season, the Blues were three points out of a playoff spot in the Western Conference, three weeks after being last in the NHL standings.
This season has been significantly different. The Blues have been among the best teams in the NHL, leading the West at 30-11-8 and six points ahead of the Colorado Avalanche in the Central Division heading into the 2020 Honda NHL All-Star Game on Saturday (8 p.m. ET; NBC, CBC, SN, TVAS).
"Obviously last year was a very different story," O'Reilly said. "We had to build and squeak in and go from there, and this year we're in a good spot right now, but the focus is still on building our game. We have to keep getting better and better and there's no perfect way to do it.
"It starts with getting into the playoffs and winning that first round and building from there. Our goal is to be playing our best hockey by the time playoffs come."
